NEW YORK (CBSNewYork/AP) — Metro-North will only be able to accommodate about one-third of the regular ridership on the New Haven line for Thursday’s commute and for the foreseeable future due to a power problem that crippled service on Wednesday, the agency announced.

The commuter rail will offer limited bus and train service for the New Haven line starting on Thursday morning, Metro-North said.

New Haven line tickets will continue to be cross-honored on the Harlem line as a result of the power issue.

REPAIRS ‘COULD TAKE WEEKS’

Connecticut Gov. Dannel P. Malloy on Wednesday advised commuters to plan for days of problems, after a power problem left hundreds of commuters stranded during the morning rush.

At a news conference, Malloy advised people to stay home and telecommute if possible. He said he was “frustrated” on behalf of everyone who uses the Metro-North line, but people have no choice but to plan for alternatives.

“Plan on a long-term lack of service or being underserved,” Malloy said. “To the extent that you can, stay home the next couple of days and telecommute.”

Bus and diesel service is also available to shuttle commuters to the Harlem line where tickets will be honored, and carpooling is also advised, Malloy said.

Malloy said it is not known how long the repairs will take. But he said he wants people to assume the problem will be prolonged.

Con Edison said in a statement that “repairs of this nature typically take 2-3 weeks.” The utility posted a photo on Twitter on Wednesday night of a crew working to repair a power feeder line.

“Con Ed is somewhat in the blind at the moment until we understand the full extent of the damage caused by the incident today,” Malloy said.

Malloy explained that one of the power feeder lines was taken offline as it was in the process of being replaced due to construction work that was under way. The other feeder line that remained in place had a critical problem that caused the outage, and the extent of the problem cannot presently be determined because the line is superheated and must be cooled with nitrogen before any assessment is made.

“I’m sure they’re gonna be looking at all sorts of options as to whether there are other power lines we can tie into their system, whether generators are practical,” Con Ed spokesman Mike Clendenin told WCBS 880’s Peter Haskell.

Metro-North was to provide extremely limited service on the New Haven line for the remainder of Wednesday.

Con Edison said it is working with Metro-North to establish alternative power sources to serve the New Haven line while crews make repairs to the failed feeder cable.

Con Edison said the railroad was doing work on the Mount Vernon substation when a feeder cable failed around 5:20 a.m. Another feeder that normally provides service to the New Haven line was already down for repairs.

COMMUTERS FACED MORNING RUSH NIGHTMARE

As CBS 2’s Lou Young reported, the promise has been one train an hour, but the reality has proved to be a little different.

“They just go right on past,” one commuter heading in to Grand Central said. “This one we’re hopefully getting on.”

He didn’t finish his morning commute until noon, Young reported.

The diesel trains bypassing some stations on Wednesday morning were jammed with riders from further up the line.

Frustrated passengers were left waiting at Grand Central and other New Haven line stations after service was suspended in both directions at the height of the morning commute.

Limited service was eventually restored around 9:30 a.m. on the New Haven line between Stamford and Grand Central using diesel locomotives, forcing thousands of commuters to cram onto crowded trains while others scrambled to find another way to work.

New Haven line tickets were being cross-honored on the Harlem line on Wednesday and that will remain in place, Metro-North announced.

Amtrak was also experiencing delays on the Northeast Corridor because of the power problem.

Some Northeast Regional trains are operating on diesel power through the affected area, Amtrak said. Acela Express service is suspended between New York and Boston. The limited service will continue on Thursday, Amtrak announced on Wednesday evening.

Additional cars are being added to Northeast Regional trains to accommodate displaced Acela Express passengers, according to Amtrak. Passengers should expect delays of up to one hour due to the diesel operation.

Service between New York and Washington was also running with delays, but is expected to resume normal service on Thursday, Amtrak said.

New Haven line direct service to and from Yankee Stadium is canceled for Wednesday night.

Of Metro-North’s 282,000 riders, 140,000 use the New Haven line.

This is the third time in recent months there has been major trouble for Metro-North riders.
